* @description:
|
|
* open a new stream to parse gzip-compressed font files. This is
|
|
* mainly used to support the compressed *.pcf.gz fonts that come
|
|
* with XFree86
|
|
*
|
|
* @input:
|
|
* stream :: target embedding stream
|
|
* source :: source stream, used to
|
|
*
|
|
* @return:
|
|
* error code. 0 means success
|
|
*
|
|
* @note:
|
|
* the source stream must be opened _before_ calling this function.
|
|
*
|
|
* calling @FT_Stream_Close on the new stream will *not* call
|
|
* @FT_Stream_Close on the source stream. None of the stream objects
|
|
* will be released to the heap.
|
|
*
|
|
* the stream implementation is very basic, and resets the decompression
|
|
* process each time seeking backwards is needed within the stream
|
|
*
|
|
* in certain builds of the library, gzip compression recognition is
|
|
* automatic when calling @FT_New_Face or @FT_Open_Face. This means that
|
|
* if no font driver is capable of handling the raw compressed file,
|
|
* the library will try to open a gzip stream from it and re-open
|
|
* the face with it.
|
|
*
|
|
* this function may return "FT_Err_Unimplemented" if your build of
|
|
* FreeType was not compiled with zlib support.
